After a few google searches I found that 1 googol (10^100) in binary is:
100100100100110101101001001011001010011000011011111001110101100001011001001111000010011000100110011100000101111
110011100010101100111001000000100011100010000100011010011111001010101010110010010000110000100010101000001011101

In decimal it is:
100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
And just for kicks, in hexadecimal it is:
1249AD2594C37D0000000000000000000000000000000000000000000000000000000000000000000000
